My manual for the LE says that the vacuum will automatically shut off if it is overheating. If you wait 30 minutes it will start again, but you obviously have a motor problem if it is over heating to start with. Can't help you with that part.

The overheat switches are doing their job here....make sure all filters are completely clean - its worth dismantling the motor compartment and blowing it out with compressed air if you can.

I can answer this question...
Why does my Electrolux LE canister vacuum shuts off after 5 minutes of use?
